US Patent:

6273248, Aug 14, 2001

Filed:

May 16, 2000

Appl. No.:

9/572822

Inventors:

Issa Batarseh - Oviedo FL
Zhihua Qu - Oviedo FL
Samuel Richie - Orlando FL

Assignee:

Unversity of Central Florida - Orlando FL

International Classification:

B65D 8557

US Classification:

2063081

Abstract:

A floppy disk cartridge adapter having a removable coin shaped memory disk. The 31/2 inch size cartridge adapter can fit into conventional personal computer disk drives. The small coin shaped magnetic disk has a diameter of approximately 1 inch, and can be easily snapped into and removed from the cartridge adapter. The coin disk fits on a spindle that is side by side to the floating drive plate used in regular 31/2 inch floppy diskettes. The spindle can be attached by various drive systems to rotate simultaneously with the rotating drive plate. One version is belt driven, another has the coin disk snap onto a spindle supported wheel whose sides frictionally rub against the drive plate wheel, and a third version has the coin disk snap onto the spindle supported gear wheel whose sides contain teeth which mateably engage like side teeth on the drive plate wheel. The coin disk can alternatively be inserted into a separate casing having a spring loaded shutter so that the conventional disk drive being used can access the magnetic sides of the coin disk by sliding the shutter. When removed from the cartridge adapter, the disk can be inserted into a small clip retainer which has a paper clip edge allowing the coin shaped disk to be portably mounted on papers, cardboard, clipboards and the like.

US Patent:

20210128248, May 6, 2021

Filed:

Jun 20, 2017

Appl. No.:

16/071311

Inventors:

- Orlando FL, US
Alexandre Clug - Palm Beach Gardens FL, US
Eytan Pollak - Oviedo FL, US
Zhihua Qu - Orlando FL, US

International Classification:

A61B 34/20
A61B 34/32

Abstract:

A robotic system for treating the skin of a patient has a robotic arm with several degrees of freedom supporting a navigation unit at an end distal to its base. The navigation unit holds a medical instrument, such as a scalpel, a microneedle tool, a plasma skin treatment device, or other medical instrument. The navigation unit has sensors that sense the distance and angle of attitude of the tool relative to the patient. A control system provides for a programmed movement of the medical instrument through a series of movements on or near the skin of the patient. Relying on the sensors in the navigational unit, the control system navigation maintains the medical instrument at a predetermined operating distance from and at a predetermined angle to the skin of the patient as the instrument is moved through the procedure, whether controlled robotically and autonomously or manually.
